BUILDING" STRUCTURE.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed May 2, 1906. Serial No. 314,885.

To all whom it may concern:

Be it known that I, ARTHUR FRANCIS WALKER, a citizen of the UnitedStates of America, and a resident of Atlanta, county of Fulton, State ofGeorgia, have invented certain new and useful improvements in BuildingStructures, of which the following is a full and clear specification,reference being had to the accompanying drawing, in which- Figure l isan exterior view of a portion of a building showing my continuous lintelbuilt therein; Fig. 2 a horizontal section taken through the lintel andlooking downward; Fig. 3 a vertical section taken on the line SMS ofFig. l; and Fig. Il a detail perspective of a form of joist hanger Iprefer employing.

The object `oaf this invention is to so employ concrete in a masonrybuilding (i. c., a structure built up of bricks or blocks) that it ispossible to materially reduce the width of the piers between the windowsand also whereby the weakening of the walls by the insertion of the endsof the floor beams therein is avoided, as more fully hereinafter setforth.

According to the preferred method of carrying out my invention l use acontinuous concrete lintel or beam (preferably reinforced with steelrods) built in place so as to bridge the tops of the masonry wall piersso as to thereby support the superimposed loads over the window and dooropenings and form a longi* tudinal tie or bond between all thepiers. Iembed in the lintel when the same is in a plastic state, at suitablepoints, suitable metal hangers and anchors for supporting the frameworkof the building and bonding it to the masonry walls, as more fullyhereinafter set forth.

Referring to they drawings annexed, A indicates the concrete lintelspanning several openings over the window-heads and bondinglongitudinally the piers between the windows. Reinforcing rods E are embedded in the lintel to give tensile strength, and an angle iron Oextends along in front of the lintel across the tops of the piers andwindowsto support a veneer of brick-Work B in front of the lintel, theinner vertical flange of this angle iron being tied or anchored to thefront face of the lintel Aby suitable rods D. F is a steel anchoring rodfor assisting in bonding the masonry of the pier to the lintel,` thelower end of this anchor being preferably Vbent horizontally, as at f,

while its upper end extends up into the lintel a suitable distance. Oneor more of these anchors F is used in each pier.

J designates a metal hanger of the usual construction for supporting theHoor beam l. One of these hangers is preferably employed at each beam orgirder Vto be supported and its outwardly bent upper ends j are embeddedin the inner face of the lintel, preferably at a point below its upperedge. Through the usual holes j in these outwardly bent ends j, nails orrods I-I may be passed to assist in bonding the hanger to the lintel. Gare metal anchors for supporting and bonding the framework to theconcrete lintel. TWO of these anchors G are preferably used with eachjoist, their outer'ends being bent down and driven or inserted in holesand grooves in the upper face of the joist, and their inner ends beingextended into and embedded in the body of the lintel, their outerextremities being preferably bent up as at g.

It' will be observed that a concrete beam, especially when reinforced,extending across a row of piers and built into place, forms a perfectcontinuous bend with the masonry of the piers supporting it, unitingeach pier with all the other piers, and differing from an ordinarylintel of metal or stone which is simply bedded in mortar and seldomspans more than one opening and therefore breaks the tie or bond at freiquent intervals.

It will be obviousl that the concrete is laid in the plastic state andsets firmly to the masonry below and to the hangers and anchors placedto support the framework and anchor the same to the lintel and wall.

ln building this structure, the floor beams or girders are firstsupported on temporary posts, the hangers .l and anchors G beingfastened to the ends of the joists in such manner that their outwardlyprojecting ends project into the space to be occupied by the lintel. Theforms or centers are placed on the under side of the lintel between thepiers and also along the front and rear sides of the lintel, and thenthe concrete and reinforcing rods are laid within the forms and theconcrete is allowed t0 harden or set. When the concrete has hardenedsufficiently the forms and the props are removed, thereby throwing theweight of the framework entirely on the walls.

It will be apparent to those skilled in the art that various mechanicalembodiments of the invention are possible and l, therefore, d0 not wishto be limited to the exact arrangement and construction shown.

What 1 claim and desire to secure by Letters Patent isz- 1. In a masonrybuilding structure having windows and masonry window piers, a concretelintel embedded in the masonry wall of the structure and extendingcontinuously across and resting upon and having direct bonding contactwith the masonry tops of said window piers and heilig reinforcedthroughout its length, means for tying the lintel to the masonry of eachpier, said means being partly embedded in the lintel, and means forsupporting and tying the Hoor system to the inner face of the lintel atintervals, said means being partly embedded in the lintel, for .thepurposes herein set forth.

2. In a masonry building structure having windows and masonry windowpiers, a concrete lintel embedded i'n the masonry wall of the structureand extending continuously across and resting upon the tops of saidwindow piers, said lintel having direct bonding contact with the masonrytops of the piers and being reinforced throughout its length, and meansfor tying the floor system to and supporting it from the -inner face ofthe lintel at intervals, said means being,r partly embedded in thelintel.

3. In a masonry building structure having windows and masonry windowpiers, a concrete lintel embedded in the 5 masonry Walls of thestructure and extending continuously across the tops of said windowpiers and being reinforced throughout its length, said lintel havingdirect bonding contact with-the masonry tops of the Window piers and thesurrounding portions of the masonry wall, andv l0 means for supportingand tying the floor system to the inner face of the lintel at intervals,said means being partly embedded in the lintel and the ends of the floorbeams terminating exterior to the inner face of the lintel.

In testimony whereof I hereunto ax my signature in "the presence of twowitnesses this 30th day of April 1906. 15
